Update documentation to specify what kind of thing an ID or DESCRIPTION is

What would you like to be added:

A lot of yardstick commands accept something like DESCRIPTION or ID, but it's not obvious what this string is. Example:

❯ yardstick label explore --help
Usage: yardstick label explore [OPTIONS] DESCRIPTION

  interact with an label results for a single image scan

Options:
  -y, --year-max-limit TEXT       max year to include in comparison (relative
                                  to the CVE ID)
  -c, --derive-year-from-cve-only
                                  only use the CVE ID year-max-limit
  --help                          Show this message and exit.

In this case, DESCRIPTION is really a result set UUID obtained by running yardstick result list and looking for the image+tool combo the user is interested in. But nothing about DESCRIPTION makes it obvious what to pass in our how to get it.

Why is this needed:

The use of generic parameter names like ID and DESCRIPTION in the docs makes it very hard to come up to speed in yardstick.

A specific example:

❯ yardstick label apply --help
Usage: yardstick label apply [OPTIONS] RESULT_ID

  see which labels apply to the given image and tool pair

Options:
  -i, --inverse                   show image lables that should not be applied
  --id                            show IDs only
  -y, --year-max-limit TEXT       max year to include in comparison (relative
                                  to the CVE ID)
  -c, --derive-year-from-cve-only
                                  only use the CVE ID year-max-limit
  --help                          Show this message and exit.

I assume that --id shows only image IDs, (as opposed to docker tags or whatever?) but this isn't 100% clear from the help text.

Another example:

❯ yardstick label compare --help
Usage: yardstick label compare [OPTIONS] [DESCRIPTIONS]...

  compare a scan result against labeled data

Options:
  --show-fns                 show all FN labels for each tool-image pair
  --show-indeterminates      show each indeterminate result for each tool-
                             image pair
  --fuzzy                    loosen restrictions on package matching
  -r, --result-set TEXT      use a named result set as description input
  -y, --year-max-limit TEXT  max year to include in comparison (relative to
                             the CVE ID)
  -j, --json                 show results as JSON
  --help                     Show this message and exit.

Descriptions of what? What's a description, and where do I get it?
